WP Multisite: Customer Site + Domain Mapping = No Upfront

Hi There,

I am currently running a custom Upfront 0.4 and Panino Version: 0.1.6 on a customer site. With no domain mapped (ie https://example.com/customer_name/) the Upfront editor works.

As soon as I add a domain mapping (i.e https://www.customer_name.com/) the menu bar overlay and link to 'Customize' (https://example.com/customer_name/?editmode=true) isn't present.

I suspect this is because the Administration URL is not sticking to the customer's domain.

Another thread (https://premium.wpmudev.org/forums/topic/domain-mapping-bug-force-https-setting-in-admin-not-saving?utm_expid=3606929-52.ZpfeUjXqSWOCaoohIqoFQQ.0&utm_referrer=https%3A%2F%2Fwww.google.com) shows where to fix this. However:

I have a discrete problem following this advice. Specifically - The Radio Button/Admin Setting - starts blank - and doesn't save when set... even after a "Options updated." message in the Network Admin > Settings > Domain Mapping Options > Administration mapping > "mapped domain" is set and "Save Changes" is clicked.

I have deleted and re-installed Domain mapping == 4.4.1.0 ==
